Samsung charged with misleading Galaxy phone owners over water resistance

Samsung charged with misleading Galaxy phone owners over water resistance The Australian Competition and Consumer Commission (ACCC) is taking Samsung to court over allegations it misled customers over the nature of various phones’ water resistance. Samsung has been depicting phones in or near to unsuitable environments such as swimming pools and oceans since 2016, the ACCC alleges, when it didn’t have a basis to make this representation. 

That’s enough water to fill 1 . 1 billion Olympic -sized swimming pools . It’s the biggest known undersea, freshwater aquifer on Earth. But more importantly, there may be other such freshwater aquifers like it throughout the world, a potentially huge natural resource on a planet with a steadily

Aquifers are underground layers of rock that are saturated with water that can be brought to the The U.S. Geological Survey website has a map of important aquifers in the contiguous United States. " Aquifers come in many shapes and sizes, but they are really a contained, underground repository of

Atlantic freshwater aquifer has enough water to fill 1 billion Olympic swimming pools© Nature.com/GMT The freshwater aquifer runs from coastal New Jersey up to the waters around Massachusetts.

If you dive deep enough off America's northeast coast you'll find something surprising under the Atlantic Ocean: freshwater.

A gigantic aquifer of mostly freshwater, hugging the coastline from New Jersey up to Massachusetts, sits below the ocean floor. It contains at least 2,800 cubic kilometers (that's about 739 trillion gallons) of liquid. That's enough water to fill 1.1 billion Olympic-sized swimming pools.

More than 20 lifeguards develop ‘swimmer’s itch’ after swim exam in man-made lake

More than 20 lifeguards develop ‘swimmer’s itch’ after swim exam in man-made lake Twenty-two Los Angeles lifeguards have filed a grievance with L.A. city officials after developing bacterial respiratory problems and skin rashes following a swim exam. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); Jasper Kim, the named lifeguard in the grievance, said he told his supervisors in the Aquatics Division of the Department of Recreation and Parks that the water in Hansen Dam Recreation Lake, a man-made freshwater lake, was unsafe for swimming due to a lack of testing for parasites.

1 .6 billion gallons of water would fill how many olympic swimming pools ? I think that , the olympics swimming pool has about a hundred litres of water . By Uthara . Answer Yes swimming is an olympic summer sport, there are different water activities like diving, length swimming etc. and

Researchers believe fresh water may have gotten trapped under the Atlantic Ocean during the Ice Age about 15,000 to 20,000 years ago. The study, which was published in Scientific Reports, said a continuous submarine aquifer system spans about 350 kilometers of the US Atlantic Coast and

It's the biggest known undersea, freshwater aquifer on Earth. But more importantly, there may be other such freshwater aquifers like it throughout the world, a potentially huge natural resource on a planet with a steadily growing population.

The discovery was made by researchers from Columbia University and the Woods Hole Oceanographic Institution while they were doing a survey of the sea floor off the US northeast coast, according to the study, published last week in the journal Scientific Reports.

Since at least the 1970s, companies in the region drilling for oil on the sea floor would sometimes hit pockets of fresh water, but it was unclear as to how much water was down there.

"We knew there was fresh water down there in isolated places, but we did not know the extent or geometry," Chloe Gustafson, a PhD. candidate at Columbia University and the study's lead author, said in a statement. "It could turn out to be an important resource in other parts of the world."

Muslim women defy French burkini ban and go swimming fully-clothed in protest (before being fined £30) The Jean Bron swimming pool in Grenoble is among many in the country that ban burkinis - a full body bikini - but 'Operation burkini' saw a group of activists break the rule and bathe for an hour. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); It was part of action by the group Citizen Alliance of Grenoble who say it a Muslim women's right to bathe in the controversial garment.

An Olympic -size swimming pool conforms to regulated dimensions, large enough for international competition. This type of swimming pool is used in the Olympic Games, where the race course is 50 metres (164.0 ft) in length, typically referred to as "long course"

Olympic size pools measure: 50 metres long, 25 metres wide, and a minimum of 2 metres deep. Could all the water a person consumes in their lifetime be enough to fill an olympic size Others have given the quantity of water but perhaps you’d like to know that such a pool could squeeze in 4

It formed after the ice age

In 2015, Kerry Key, a geophysicist at Columbia University, and Rob Evans, a geologist and geophysicist at Woods Hole Oceanographic Institution, dropped special instruments to the ocean floor near those old oil drill holes to measure electromagnetic fields and map the water. Since freshwater is not as good of a conductor of electromagnetic waves as salt water, the freshwater stood out.

Their research showed the aquifer, which lies about 600 feet below the ocean floor, ran from the shoreline out to as far as 75 miles away from the coast.

So how did the freshwater get there? The researchers theorize the fresh water in the aquifer was ice that melted after the last ice age and got trapped in sediment that was rocky. They also think that the aquifer is being fed by underground runoff from the shore.

Gustafson, Key and Evans hope their research can be used to pinpoint other undersea coastal aquifers around the world that could be "a potential resource in regions where onshore freshwater resources have diminished."

The freshwater in the aquifer would still need to undergo desalinization before it could be used for drinking water, because the water is slightly salty since it does mix a little with the saltier ocean water.

Swimmer dies from rare brain-eating amoeba at North Carolina water park, reports say.
A swimmer has died after contracting a rare brain-eating amoeba from a water park in North Carolina, according to reports. A swimmer excercises in St. Margret's Bay, close to the White Cliffs of Dover on the southeast coast of England on July 25, 2019, as Britain experiences a heatwave. - A dangerously intense heatwave across much of Europe is to spike even higher Thursday after already breaking records in several countries, impacting rail traffic and sending people in search of shade and water.
